1-9z For DLDP to work properly, enable DLDP on both sides and make sure these settings areconsistent: the interval for sending Advertisement packets, DLDP authentication mode, andpassword.z DLDP does not process any link aggregation control protocol (LACP) events. The links in anaggregation are treated as individual links in DLDP.z For DLDP to operate properly, make sure the DLDP version running on devices on the two sidesare the same.Enabling DLDPTo properly configure DLDP on the device, you need to first enable DLDP globally, and then enable it oneach port.Follow these steps to enable DLDP:To do… Use the command… RemarksEnter system view system-view —Enable DLDP globally dldp enable RequiredGlobally disabled by defaultEnterEthernet portviewinterface interface-typeinterface-numberEnterEthernetport viewor portgroupviewEnter portgroup viewport-group manualport-group-nameEither of the two is required.Configurations made in Ethernet portview apply to the current port only;configurations performed in port groupview apply to all the ports in the portgroup.Enable DLDP dldp enable RequiredDisabled on a port by defaultz DLDP takes effect only on Ethernet interfaces (optical or copper).z DLDP can detect unidirectional links only after all physical links are connected. Therefore, beforeenabling DLDP, make sure that optical fibers or copper twisted pairs are connected.Setting DLDP ModeThere are two DLDP modes:z Normal mode: In this mode, DLDP does not actively detect neighbors when the correspondingneighbor entries age out. The system can identify only one type of unidirectional links:cross-connected fibers.
